Simultaneous Determination of Seven Active Constituents in Different Parts of Dandrantherna Morifolium ( Ramat. ) Tzvel. by HPLC-DAD / 中国药师

ABSTRACT

Objective:To develop an HPLC-DAD method for the simultaneous determination of seven active constituents chloro-genic acid, 3,5-dicaffeoylquinic acid,linarin, luteolin-7-O-β-D-glucoside, apigenin-7-O-β-D-glucoside , luteolin and acacetin in the different parts of Dandrantherna morifolium( Ramat. ) Tzvel. Methods:The chromatographic separation was performed on a Diamonsil C18 column (200 mm × 4. 6 mm,5 μm) with 0. 2% phosphoric acid-acetonitrile as the mobile phase with gradient elution at the flow rate of 1 ml·min-1 . The detection wavelength was set at 348 nm,and the column temperature was maintained at 30 ℃. Results:Chlorogenic acid, 3,5-dicaffeoylquinic acid, linarin, luteolin-7-O-β-D-glucoside, apigenin-7-O-β-D-glucoside , luteolin and acacetin was linear within the range of 0.014-0.560 μg(r =0.999 5) ,0.031-1.260 μg(r =0.999 6), 0.022-0.900 μg(r =0.999 8), 0. 036-1. 440 μg(r=0. 999 6),0. 029-1. 160 μg (r=0. 999 7) , 0. 005 5-0. 220 0 μg (r=0. 999 8) and 0. 006 5-0. 260 0 μg (r=0. 999 9), respectively. The average recovery was 97. 91%, 97. 91%, 97. 55%, 96. 43%, 96. 44%, 97. 07% and 97. 48%, and RSDs was 1. 24%, 1. 29%, 1. 48%, 1. 83%, 0. 67%, 1. 88% and 1. 80%, respectively. Conclusion: The method is convenient, accurate and reproducible in the quality control of the multicomponents in different parts of Dandrantherna morifolium( Ramat. ) Tzvel.
